A Dielectric Resonator Oscillator for DSRC with Improved Phase Noise Characteristic
Abstract
In this paper, a DRO (Dielectric Resonator Oscillator) with high stability in DSRC(Dedicated Short Range Communication) is designed and fabricated. The DRO shows the phase noise characteristic of -109.3 dBc/Hz at 100 kHz offset from the fundamental frequency. The output power of 11.53 dBm, and the second harmonic suppression of 55.33 dBc for the DRO are obtained. This DRO with high stability of the phase noise characteristic can be used for the system in DSRC.
